752 Series – BackPack Valve Actuator
Introduction
The 752V BackPack Series diaphragm valves are simple to use and will operate many millions of cycles
without maintenance. Incorporating advanced miniature solenoid technology with actuation speeds as
low as 5–6 milliseconds, cycle rates exceeding 80 hertz can be achieved. Fast valve actuation speeds
result in extremely small deposit capability.
Direct mounting of the BackPack Valve Actuator pod to the valve’s actuating air cylinder body improves
process variation for better dot-to-dot consistency. BackPack’s low profile, compact design provides
clearance for optimum center-to-center mounting.
Made of lightweight materials for easy end-of-arm installations, the BackPack Valve Actuator pod can
also retrofit to all 752V Series model valves. The BackPack Valve Actuator is designed for easy removal
and maintenance.
Each valve is shipped with a BackPack Valve Actuator pod, dispensing tip adapter, fluid inlet fitting and
5-foot actuating air hose, and tip kit.
